To all whom it may 001mm:

Be it known that I, GEORGE D. BURTON, a citizen of the United States of America and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented certain new and useful Improvements in the Process of Manufacturin' Ice- Cream, Sherbet, &c., of which the 0 lowing is a specification.

The invention relates to processes of manufacturing ice cream, sherbet, etc;, whereby the production of such articles of food may be greatly facilitated while at the same time a reatly improved product will be obtained, ee from all impurities.

The invention consists in certain novel features and arrangement of parts in the machine whereby said novel process may be carried out.

Of the drawings: Figure 1 representsa perspective View of an apparatus embodye ing the features of this invention. Fig. 2 represents a vertical section of the same on line 2-2 on Fig. 3,.looking in the direction of the arrow. Fig. 3 represents a horizontal section on line 3-3 on Fig. 2, and Fig. 4 represents a vertical section on line 44 on Fig. 3 looking in the direction of, the arrow.

Similar characters designate like parts throughout the several figures of the drawmgs.

In the drawings, 10 represents a tank of any well-known construction, open at the top and provided with bearings 11 for the trunnions 12 and 13 secured to the revoluble receptacle 14, the interior of which is provided with a plurality of mixing blades 15 extending radially toward the axis of said receptacle. The trunnion 13' has mounted thereon a driving pulle 16 and a loose pulley 17. Motion may e imparted to the' receptacle 14 through the medium of the fast pulley 16 to revolve the same at any desired speed.

Tht rec t-acle 14 is provided with a door 18 throufi which is mserted the ingredients from which the ice cream, sherbet, etc,

is to -be'-made. On each of the trunnions 12-13 is mounted an insulating disk 19 the outer periphery of-whlch is provided with a copper rmg 20 which is connected through the trunnions 1213 by means of the con- .nector 21 to the electrodes 22 secured to the inner face of the heads 23-24- of said revoluble receptacle 14. The heads 25 ofthe tank 10 are each provided with a stud 26 insulated from said head and supporting a brush 27 contacting with the annular coplated from the-floor by the plates 33 said.

frame 32 being provided with for the trunnion 13.

A direct current of electrictiy is usually used of from seventy-five to five hundred Volts more or less and varying in amperage from two to two hundred more or less, according to the size of the receptacle and the quantity of ice cream or other product to be manufactured, this current belng obtained from any suitable source.

In the process of manufacturing ice cream, sherbet, and other substances by means of the apparatus described the ingredients from which said substances are to be ,made are inserted in the receptacle 14 through the opening closed by the door 18 and said door is then closed and securely fastened. The tank 10 is suplplied with a suitable freezing compound suc as ice and rock salt or other suitable material and the driving belt is a bearing 34 shifted to the fast pulle to cause the receptacle 14 to be revolve at a high rate of speed. The switch 28 is then operated to connect the apparatus with an electrical supply and a current of electricity is thereby assed from one electrode 22 to the electr e at the opposite end of said receptacle, the electricity passing through the ingredients contained within the receptacle. nipurities, which when resent might contaminate the cream and other in redients, will in most cases, by the action 0 the electric current thereon, while any germs or microbes which might possibly exist in said cream will be destroyed and further pro agation prevented. Ice cream, sherbet and other similar substances manufactured by this process are superior to similar products manufactured by the ogrocesses heretofore employed while the pr ucts obtained through this process are perfectly hygienic and free from all impurities.

It is believed that from the foregoing the be rendered innocuous,

operation of the invention will be thoroughly understood.

Claims.

'1. The process of. manufacturing ice cream, sherbet, etc., which consists in placing the ingredients thereof in a receptacle revoluble .in a tank containin .a freezing compound, and subjecting said ingredients to the action of an electric current.

2. The process of manufacturing ice cream, sherbet, etc., which consists in placing the ingredients thereof in a receptacle provided with an electrode at each end, re-

volvmg said receptacle in a tank containing a freezin compound and assln an electrlc current through the lngre ients y means of said electrodes.

3. The process of manufacturing ice I sherbet, etc., which consists in placcream, ing the ingredients thereof in a rece tacle provided with an electrode at each en and havin a pluralit of radially disposed mixing b ades, revo ving said receptacle in a tank containing a freezing compound, and passing an electric current through the ingredients by means of said electrodes.

4. The process of manufacturing ice cream, sherbet, etc., which consists in placing the ingredients thereof in a receptacle having electrodes and a plurality of radially disposed mixing blades, revolving said receptacle in a tank containing a freezing compound, and passing an' electric current through the .ingredients by means of said electrodes.

Signed by me at Boston, Massachusetts, this 25th day of January, 1906.
